LD39100PURY ST LDO Voltage Regulator | 6-DFN(3x3) | 1A Output, 200mV Dropout

Product Overview

The LD39100PURY from STMicroelectronics is a high-performance, low-dropout (LDO) voltage regulator designed to deliver up to 1A of output current with a dropout voltage as low as 200mV at full load. Housed in a compact 6-DFN (3x3mm) package, this device offers excellent line and load transient response, making it ideal for space-constrained applications requiring stable and efficient power delivery. The LD39100PURY features a wide input voltage range from 1.5V to 5.5V and provides an adjustable output voltage from 0.8V to VIN, with a fixed output option available. Its low quiescent current (typically 30µA) and shutdown current (<1µA) contribute to extended battery life in portable devices. The device includes built-in protection features such as overcurrent, overtemperature, and reverse current protection, ensuring robust operation in demanding environments.
